Mine got up on all fours for the first time tonight!! I was putting my hands behind his feet and letting him push off to scoot around, and he got his legs up beneath himself and stayed there for 5 seconds, then flopped on his tummy. But it was so exciting. I can't believe how fast this happens! 2 months ago, he was just starting to lift his head while on his tummy!

My little guy is so close!! He rocks on all fours, he can plank, which is amazing to me, haha. He is great at moving backwards, sideways and rotating himself. He has gotten a tiny bit of forward movement by propelling himself forward after rocking, but no actual crawling yet.
